The small divisors problem in the quantum Kicked Rotator (III)
Por Luís Pereira (Instituto Superior Técnico).
Abstract: The Kicked Rotator is one of the central models in studies of chaos theory. Its quantization was the subject of great interest in the 1980's, but since the 1990's, interest faded. I hope to rekindle interest in this subject.

How to find a Fractal function from real data?
Speaker: Cristina Serpa (CMAFcIO).
Fractals are beautiful mathematical objects and are everywhere. It is possible and widely known how such objects are constructed mathematically. A fascinating challenge is how can a fractal pattern be mathematically found from real data? Let us remember that a fractal is chaotic, a dynamic system very sensitive to initial conditions. In this seminar I will present a method that I developed to find fractal functions that approximate real data.
